This PR changes Node.js/npm compatibility layer to use polyfills for built-in Node.js embedded in the snapshot (that are coming from "ext/node" extension). As a result loading `std/node`, either from "https://deno.land/std@<latest>/" or from "DENO_NODE_COMPAT_URL" env variable were removed. All code that is imported via "npm:" specifiers now uses code embedded in the snapshot. Several fixes were applied to various modules in "ext/node" to make tests pass. --------- Co-authored-by: Yoshiya Hinosawa <stibium121@gmail.com> Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com> |

Deno Core Crate
The main dependency of this crate is rusty_v8, which provides the V8-Rust bindings.
This Rust crate contains the essential V8 bindings for Deno's command-line interface (Deno CLI). The main abstraction here is the JsRuntime which provides a way to execute JavaScript.
The JsRuntime implements an event loop abstraction for the executed code that
keeps track of all pending tasks (async ops, dynamic module loads). It is user's
responsibility to drive that loop by using JsRuntime::run_event_loop
method -
it must be executed in the context of Rust's future executor (eg. tokio, smol).
Rust functions can be registered in JavaScript using deno_core::Extension
. Use
the Deno.core.ops.op_name()
and Deno.core.opAsync("op_name", ...)
functions
to trigger the op function callback. A conventional way to write ops is using
the deno_ops
crate.
Documentation for this crate is thin at the moment. Please see hello_world.rs and http_bench_json_ops.rs as examples of usage.
TypeScript support and lots of other functionality are not available at this layer. See the CLI for that.
